Hello,
I've a Bassman aa864 and the guitar channel make hum thru the speaker and I have'nt any guitar sound. The hum interacts with the volumen pot, if I pull of the V3 valve the hum disapear. The bass channel Works well.
I tried to change valves, but the hum persist.
Any idea?
Thanks.

Does the hum appear with plugged in guitar or unplugged or in each case.
Perhaps, the input jack is defective over the years.
